Solid State Relays are an important piece of equipment for any facility as they enable smooth, efficient, and reliable operations. One of the main benefits of Solid State Relays is their ability to control components without physically touching them, resulting in lower maintenance costs, increased safety, and improved performance. The H12WD4825PG is an example of a solid-state relay which offers a wide application field and reliable performance. In this article, we’ll discuss the application field and working principle of the H12WD4825PG.

The H12WD4825PG is a three-terminal, single-pole double-throw (SPDT) relay suitable for controlling light loads such as resistive track lighting, motors, and solenoids. It is designed for use with an AC line voltage of up to 480 volts and provides a maximum safe operating temperature of 75°C. It also features a built-in SPRC (Surge Protective Resistor Circuitry) circuit designed to prevent overvoltage and has a mechanically and thermally latched relay function.

The H12WD4825PG is an ideal device for controlling track lighting and other light loads in commercial settings such as theaters or restaurants. It can also be used to control light-load motors and solenoids in industrial applications such as pumps and valves. Additionally, the H12WD4825PG can be used as part of a control circuit for light loads in the manufacturing industry.

It is important to understand the working principle of the H12WD4825PG in order to get the most out of it. The relay is activated by an electrical current passing through a coil and energizing a magnetic core. This causes a magnetic field to be generated which attracts a movable core, and thus closes the connections. When the current is turned off, the movable core returns to its original position and the relay reverts to its default, open-circuit, position. This also means that the relay will not turn off until the voltage is completely removed, allowing for efficient and safe operation.

The H12WD4825PG is a great choice for light load applications such as track lighting, motors, and solenoids. It is designed for use with AC line voltages, up to 480V and features SPRC protection as well as a mechanically and thermally latched relay. Its working principle is based on a current passing through a coil and generating a magnetic field, which in turn closes the connections and turns on the relay. This allows for smoother, more reliable operations which require less maintenance and improved performance in the long run.
